BACKGROUND

Inflatable pads are inflated air pads, are mainly used for outdoorsports or outdoor recreation, and can be used together with tents. Ingym classes or sports competitions, at many times, because there is notenough space, temporary arrangement is required for performing sit-upsor high jumps and other competitions. Nowadays, because beach recreationand beach bathing are popular, inflatable pads are available for peopleto enjoy themselves on the beach. Inflatable pads on the marketgenerally include two types, inflatable/deflatable pads andnon-inflatable/non-deflatable pads, wherein the inflatable/deflatablepads can be inflated/deflated as needed, have the characteristics ofsimple operation, flexible use and high portability, and are morefavored by people. However, the inflation operation efficiency of theinflatable pad is influenced because a horizontal sealing line and anair passage of the inflatable pad are insufficiently reasonable inposition, and the use experience is influenced because the inflatablepad is subjected to a large stress in the middle and is easily collapsedduring use.

DETAILED DESCRIPTION

The utility model is further described below in detail in combinationwith the drawings and embodiments.

As shown in FIG. 1 to FIG. 3, an inflatable pad of this embodiment,comprising a pad body 1, wherein the pad body 1 is formed by twoinflation gaskets by hot-pressing surrounding edge plastic by a hotpress, and the inflation gaskets may be made of TPU coated cloth. Thepad body 1 comprises a region formed by a length and a width to supporta human body, wherein the length extends from a first end 11 to a secondend 12, and the width extends from a third end 13 to a fourth end 14.

The inflation gasket at one side of the pad body 1 is provided with aninflation interface 7 internally communicated with the inflatable pad, arubber cap plug is provided on the inflation interface 7, and the rubbercap plug is opened/closed to control the inflatable pad to maintain aninflation or deflation state. The inflation interface 7 may be connectedwith an inflation pump to realize quick inflation.

Corrugated horizontal sealing lines 4 formed by hot-pressing areuniformly distributed on the inflation gasket in the horizontaldirection, and after the inflatable pad is inflated through theinflation interface 7, the region between two horizontal sealing lines 4is inflated to form a corrugated air chamber 6. The inflatable pad ofsuch shape has higher degree of comfort, and can be better adapted touneven ground.

Circular sealing rings 2 formed by hot-pressing are provided at bothends of the horizontal sealing line 4 respectively, the circular sealingring 2 is formed by nesting two concentric circles with different radii,and the diameter of the outer circle of the circular sealing ring 2ranges from 6 mm to 30 mm. The circular sealing ring 2 increases thestress intensity of the inflatable pad. A gap between the circularsealing ring 2 and the horizontal sealing line 4 is used as an airpassage 5, and the width of the air passage 5 ranges from 3 mm to 30 mm.The air passage 5 increases the inflation efficiency.

A plurality of vertical sealing strips 3 formed by hot-pressing aredistributed in the middle of the inflation gasket in the verticaldirection, and after the inflatable pad is inflated through theinflation interface 7, the region between two vertical sealing strips 3is inflated to form an upright air chamber 6. The use experience isoptimized because the inflatable pad is enhanced in stress capability inthe middle and is not easily collapsed during use.

Both ends of the vertical sealing strip 3 and the horizontal sealingline 4 are in a semicircular arc shape, to disperse pressure and preventthe vertical sealing strip 3 and horizontal sealing line 4 which areformed by hot-pressing from cracking at the edge when the inflatable padis subjected to an overlarge stress.

When used, the inflatable pad is unfolded, the rubber cap plug on theinflation interface 7 is opened, the inflation interface 7 is aimed by amouth or an air nozzle of the inflation pump, a high-pressure air flowflows into air passages 5 at both sides from the air chamber 6 at thebottom of the inflatable pad, and the inflatable pad is inflated at thesame time, so that the inflatable pad is internally filled with air andis expanded, the inflation speed is increased, and the inflation time isshortened; then, the air pressure is adjusted to the use comforthardness; the air nozzle is closed, and the rubber cap plug is closed;during deflation, the rubber cap plug on the inflation interface 7 isopened, the inflatable pad is rolled from the other end with theinflation interface 7 and is folded repeatedly, air is forcefullyextruded, and the deflated inflatable pad is rolled after the rubber capplug is closed.

A technical problem to be solved by the utility model is to provide aninflatable pad with a more reasonable structure aiming at the problemsof the prior art. The utility model provides an inflatable pad providedwith corrugated horizontal sealing lines in the horizontal direction ofa pad body, provided with circular sealing rings at both ends of eachhorizontal sealing line respectively, and provided with a plurality ofvertical sealing strips in the middle in the vertical direction of thepad body. Compared with the prior art, the inflatable pad has theadvantages of simple structure, convenient use and comfort.
